Patented .lune 13, 1933 PAT LOUIS V. ARONSON, OF NEVJARK, JERSEY,ASSIGNOR TO ART METAL W'ORKS, INC., A CORPORATION OF NEW JERSEYALTOMIZER Application led January 25, 1930. Serial No. 423,509.

My invention relates to atomizers of a readily portable and simplecharacter.

My invention relates to an atomizer adapted i particularly for medicinaluses, the arrange- .ment of parts being such that the atomizer is highlyefficient and satisfactory in operation.

Further advantages, characteristics and objects of my invention willbecome apparent from the following description taken in connection withthe accompanying drawing.

My invention resides in the atomizer, the device, and in the featuresand details of construction of the character hereinafter described andclaimed.

For an illustration of one of the many forms of my invention, referenceis to be had to the accompanying drawing, in which Figure l is aperspective view of an atomizer constructed in accordance with myinvention.

Fig. 2' is a vertical sectional view of the atomizer of Fig. l and istaken substantially on the line 2--2 of Fig. l looking in the directionof the arrows.

Fig. 3 is a vertical sectional view of the atomizer shown in Fig. l andis taken substantially on the line 3-3 of Fig. 2 looking in thedirection of the arrows.

Fig. 4 is an enlarged, vertical sectional view of the atomizingconduits.

Fig. 5 is a perspective view of latching mechanism for the pump plunger.

Fig. 6 is a perspective view of a modified closure device.

Referring to the drawing, C represents a casing or container of anysuitable configura-- tion and herein shown as comprising a base ladapted to rest upon any suitable support or surface. Upstanding fromthe base l is the casing side wall structure 2 which may be andpreferably is generally circular in hori- Zontal cross-sectionalconfiguration and shaped to form an upper throat section 3 merginguniformly toward the longitudinal axis of said casing C. Carried by saidthroat section 3 is a bushing-like member 4 having a passage into whichis threaded the stem 5a of a tube 5, the upper end of which,

preferably, is tapered exteriorly as indicated at 5b, Figs. l, 2 and 8.

Disposed interiorly of the casing C is a pump casing 6 sealed from thehereinafter described liquid medium in the casing C and 5scircular invertical cross-section, Figs. 2 and 3. The pump casing 6 may be flangedat one end, as at 6a, and such fianged section may be welded orotherwise suitably secured to the interior surface of the casing C, theside wall structure 2 of which is cut away to form an aperture oropening in alinement with said pump casing 6. Threaded into aninteriorly threaded section of the pump casing 6 and closing saidaperture is a plug 7 c5 apertured to freely receive a reciprocatory pumpplunger terminating, at one end, in a suitable knob 8a. At its otherend, the plunger 8 may have a threaded shank 8b receiving a first washer9, a sheet l() of leather, Zu suitable rubberized fabric or the likeadapted to take a flanged configuration as shown, and a second washer1l. A nut 12 threaded to the stem 8b serves to retain the parts lastdescribed in assembled relation.

The plug 7, washers 9 and ll, and the sheet 10 may have aperturesdisposed in alinement as illustrated for passing air to the interior ofthe pump casing 6. A suitable readily oscillatable member 13 may bedisposed over the outlet of the aforesaid apertures and retained inposition by the nut l2. The mem ber 13 functions as a flap valve toadmit air to the interior of pump casing 6 through the aforesaidapertures when the plunger 8 moves in one direction and to preventpassage of air through said apertures from said pump casing when theplunger 8 moves in reverse direction.

The pump plunger 8 is biased toward and into the position shown in Fig.2 in any suitable manner. To this end and as illustrated, a helicalspring le is disposed interiorly of the pump casing, one end thereofbeing seated about a knob 'l5 formed on the interior sur- 95 face of thepump casing 6 and the other end thereof being seated about the nut l2.

In the example shown, the pump plunger 8 is releasably latched in itsinner position, this position being the one where the spring 14 is undermaximum compression, by providing on said pump plunger a latch member 16which is coactable with a headed pin 17 projecting from the aforesaidcap 7 if desired.

Disposed within the casing C is any suitable liquid medium L which maybe introduced thereinto in any suitable manner, for example, through anopening in the casing side wall structure which is normally closed by aplug 1.8 threaded thereinto, said plug 18 preferably having an exteriorsection 18a adapted to be manually grasped and manipulated.

Dipping into the liquid medium L is a liquid-passing tube or conduit 19which, adjacent its lower end, is curved around the pump casing 6 andwhich extends upwardly through the tube 5 and terminates somewhat belowthe upper surface ofthe latter in a laterally directed tip or nozzle19a. A second tube or conduit 2O is disposed interior-ly of the casingC, this conduit opening into the pump casing 6 adjacent the end thereofremoved from the plug 7, being curved so as to pass upwardly through theaforesaid tube 5 and terminating in a tip or nozzle 20a disposed belowand placed just to the side of the aforesaid nozzle 19a.

The tube 5 is adapted to be closed in any suitable manner and this maybe accomplished in a variety of ways. Thus, in Figs. 1, 2 and 3, a cap21 is shown as adapted for disposal or disposed about said tube 5, saidcap 21 seating on the member 4. Vhere a cap is thus utilized, it may benon-detachab'ly secured to the casing C by a flexible member 22. Or, asshown in F ig. 6, the upper end of the tube 5 may be threaded,preferably interiorly, for the reception of a threaded plug 23. Or, ifdesired, any other suitable arrangement may be utilized for the purposelast described.

When the device is not in use, the pump plunger 8 should be in its innerposition with the latch member 16 behind the head of pin 17.

To place the device in operation, the cap or closure member for the tube5 is removed and then the knob 8a is rotated slightly to disengage thelatch member 16 from pin 17. After so doing, the casing C may be held inone hand and the pump plunger reciprocated by thumb or linger actionthereby pumping air through the conduit 20. The air passing outwardlythrough the nozzle 20ct at relatively high velocity sweeps past thenozzle 19a of conduit 19 thereby causing rise of some of the liquidmedium L through said conduit 19 and atomization thereof beyond the endof nozzle 19a, the atomized mixture passing, at relatively highvelocity, through and from the upper end of tube 5.

After completion of the desired atomizing action, the pump plunger 8 maybe latched in its inner position in an obvious manner. This should bedone before the cap 21, plug 23, or equivalent, is placed in position tominimize or obviate danger of leal*- age at the upper end of tube 5.

The device herein disclosed is intended, ordinarily, for medical usesand hence the liquid medium L usually is a disinfectant, medicinal orysome soothing agent. The tapered end 5b of tube 5 is provided so thatthe tube 5 may be readily inserted in a nostril, as desired.

While the invention has been described with respect to a certainparticular preferred example which gives satisfactory results, it willbe understood by those skilled in the art after understanding theinvention, that various changes and modifications may be made withoutdeparting from the spirit and u scope of the invention and it isintended therefore in the appended claims to cover all such changes andmodifications.
